Advice on hooking up my DTV convertor box?

I have a Sears 12 inch black and white tv from 1982. It is NOT cable red (no av jacks). I don’t want to toss it as it still works great. The antennas on the tv are as follows: a straight antenna (can telescope) screwed into the tv and a loop antenna in the back of the tv. Looking at the back of the tv, on the left hand side several inches below the straight antenna are 4 phillips screws and the letters VHF and UHF. White and gray wires with “U” shaped pieces of metal are held down by the screws? Any suggestions for hooking up the DTV convertor box? I do have a separate set of “rabbit ears” and hooked it up to the “antenna in” hole on the back of the convertor box. However, I do not know where to run the wire from “antenna out” to the tv. Where do I hook up the the wire from the “antenna out” hole? I do have a 75 ohm to 300 ohm balum (transformer). Thanks.

There are two types of 75 ohm to 300 ohm baluns. The kind you need looks like a cylinder with two wires sticking out the end. The two wires attach to the VHF screw terminals. Disconnect the existing leads from the VHF terminals. If you aren’t going to reuse the UHF loop, you can leave it attached to the UHF terminals. It will still pick up analog channels 14-69 until they are shut down.

You may need a new antenna but first you should figure out what kind of antenna you need. Go to the first link below and look at the “post transition” chart for your area. You need to find out if your local “real” channels are all UHF (14-69) or if you also have VHF (2-13) stations.

If all the “real” channel numbers are between 14 and 69, then you can probably use the current UHF loop antenna with your converter box. To attach the loop to the box you will need the other type of balun; the type that is “L” shaped with two screw terminals.

If the loop doesn’t give you good enough digital reception on “real” channels 14-69, then you will need a better UHF antenna.

If you have local digital stations on “real” channels 2-13, you are probably better off buying a new TV VHF/UHFantenna. If you get good analog reception with your current antennas, a $10 basic rabbit ear (with built in UHF loop/figure model will probably be OK.

We had a 'whale of a time "and the whale said thanks.

One sunny September morning while returning from a dive in crystalline waters Mauritius I received a distress call on VHF radio ships. Being a dive instructor and owner of a diving center on the tropical island of Mauritius was doing what we usually do each day. Diving. But this day would come one day be unusual.

Prodive limited Diving in Mauritius is a professional scuba diving school and diving center. I've been in business for 24 years in Mauritius and the oldest instructor and owner of the center diving on the island. We had taken delivery of our new luxury 46 ft dive boat cruise complete with cabins, showers, head, and the kitchen. Equipped with two turbo Ford six inboard of the cylinder. I was at the helm enjoying the feel of a new charter dive successfully and luxury of the new big dive boat. Behind of me was a very happy group of divers and dive masters and instructors all my talking about what we saw and what happened in diving. This is the usual chatting and receiving information going after immersion and is part of the sensation of diving. While the government the boat through the step (a hole in the barrier reef surrounding Mauritius) boats VHF radio crackled and the noise coming from behind and the sound of the engines I could do that there was no distress call. Someone asking all dive centers in the north to come and help save a whale.

After divers returned to our base I told my crew and diving equipment there was a beached whale in some way. With no doubt that we decided to go see what had happened. I was very enthused and excited at the prospect of an adventure and this gave me the opportunity to test the new boat in a long race.

Apparently, the whale had run aground on "Turtle Bay" which is a horseshoe shaped bay, south of our base, but still in the northwest of the island. The local radio station I was playing good music and boat engines were humming as they sailed south to Turtle Bay. It took about half an hour to reach the top north of a rocky crops that form the edge of one side of the horseshoe-shaped bay. I cut accelerators to reduce boat speed when we entered the control bay for the passage of the barrier reef and summarize what was happening inside the bay.

The bay was alive. The surface was boiling with divers splashing. Disorganized and everywhere, swimming in all directions. Amidst all this mess could see some white buoys floating on the surface and then disappear under water. A source of water spray into the air as the whale surfaced out of the divers who were splashing clumsily. Everyone seemed to be willing to help and at the same time, reluctant to address the plight of the humpback whale. Buoys and bits of rope and net were floating everywhere. They had to cut away at the end of the mass of the tangled web trailing behind the whale. But this was not the solution. I knew we had to get to where it attaches to the story whales and make it disappear at once. My diving equipment which was ready and snorkel masks and fins. We could see the fishing net sprinkled with white polystyrene 'buoys entangled in the tail of the whale. This mass of net, rope and buoys to prevent the whale swimming causing tremendous drag. As the whale away from the divers in the water I tried to judge the direction in which they move and turned the wheel quickly to maneuver the boat gently forward to the leadership position of the whale would take. The dive team, a group of five diving instructor and dive masters for 'diving knives in their hands. Some had a typical normal fish knife Mauritius with a long blade, very flexible and can easily be tuned to cut through anything. Everything was happening very quickly.
